Objective:To compare the oncology effect and risk between hepatopplenectomy and conventional hepatectomy for hepatocellular carcinoma patients with hypersplenism, so as to provide guidance for clinical application.Methods:One hundred and eighteen patients with hepatic carcinoma with hypersplenism in the Private hospitals of Zhejiang Province Yiwu were studied retrospectively. Patients were divided into 2 groups according to different operation methods: combined hepatosplenectomy group and conventional hepatectomy group with 59 cases in each group. Blood routine, liver function, complication and tumor effect (local recurrence, distant metastasis and 1, 3, 5 years survival rate) was compared between two group.Results:There was no significant difference in operation time, intraoperative blood loss and hospitalization time between the two groups ( P>0.05). Compared with that of the control group, the clinical total effective rate of the combined group was significantly increased: 94.92% (56/59) vs. 79.66% (47/59), P<0.05; there was no significant difference in the incidence of complications between the two groups ( P>0.05); the two groups were followed up to August 1, 2019. The median survival time of the two groups was significantly higher than that of the open group (29 months vs 22 months) ( P<0.05); the local recurrence rate, distant metastasis rate, 1, 3 and 5-year survival rate between the two groups were statistically significant ( P<0.05). The platelet and white blood cells in the combined group were significantly higher than those in the control group after 7 days′ treatment: (264.48 ± 75.37) × 10 9/L vs. (153.53 ± 42.11) × 10 9/L, (7.86 ± 1.43) × 10 9/L vs. (3.48 ± 1.32) × 10 9/L, P<0.05. Compared with that of the control group, alanine aminotransferase and aspartate aminotransferase were significantly decreased: (49.42 ± 31.88) U/L vs. (84.22 ± 43.95) U/L, (36.50 ± 21.50) U/L vs. (49.98 ± 35.63) U/L, P<0.05. Conclusions:Compared with conventional hepatectomy for hepatocellular carcinoma patients with hypersplenism, combined hepatosplenectomy can effectively promote the increase of peripheral blood PLT and WBC and the recovery of liver function without increasing the risk of surgery, and the long-term follow-up results are more satisfactory, which has high clinical application value.

BACKGROUND: Tissue engineering plays an important role in treating rotator cuff injury. Promoting the healing of injured rotator cuff and preventing adhesion by regulating growth factor expression are main functions. OBJECTIVE:To compare the effects of corticosteroids and hyaluronic acid on the expressions of epidermal growth factor (EGF),platelet-derived growth factor (PDGF),transforming growth factor ? (TGF-?) and basic fibroblast growth factor (bFGF) in injured rotator cuff. DESIGN,TIME AND SETTING: The randomized controlled animal experiment was performed at the Animal Experimental Center,School of Medicine,Shanghai Jiao Tong University from July to September 2007. MATERIALS: Totally thirty-six Sprague-Dawley (SD) rats were randomly assigned into four groups: normal group (n=6),rotator cuff injury group (n=6),hyaluronic acid group (n=12) and corticosteroids group (n=12). METHODS: Full-thickness defects across 50% of the total width (5 mm) of the bilateral infraspinatus tendon were excised. Models of rotator cuff injury were created at the synovium. 0.05 mL hyaluronic acid was injected into the subacromial bursa mucosa in the hyaluronic acid group,whereas 0.05 mL corticosteroids in the corticosteroids group. MAIN OUTCOME MEASURES: At three and six weeks after injury,the infraspinatus were harvested to detect EGF,PDGF,TGF-? and BFGF by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: By using corticosteroids treatment,the expression of EGF remained greater at the six weeks than twofold at the three weeks; the expression of EGF after hyaluronic acid treatment greatly decreased at six weeks (P
